Mi piexe shows a device for grinding bulk materials, vertical section

A device for grinding bulk materials includes a housing 1 in which disks 2 and 3 are mounted one above the other, forming a soy discharge ring slit 4 The upper disk 3 is made and a loading opening 5 and is mounted with the possibility of reciprocating movement along the vertical Lower disk 2 made hollow and yulu-yat rotation from the drive. Inside the nickle of the disks 2, a vertical bar was installed. C received rotation from the drive. The top end and the HI shaft 6 are provided with rods ssi 7, mpi1.cm. The rods-axes of the upper rus are placed between the rods of the lower rus evenly around the circumference. Balls 8 of different diameters are mounted on the stem x-ax x 7, separated by springs 9 and increasing towards the periphery of the disks. Balls 8 are knocked out by ksznavk 10 with a segment file made on working surfaces of the top 3 and bottom 2 disks with a shift in the radial direction. The radii of the grooves 10 are larger than the radii of the balls corresponding to them 8 using the bolt gvv 12. Springs 13 are placed between the upper disc 3 and the stops 11, and the bolts 12 are omitted inside the springs 13. The position of the stops 11 relative to the housing 1 in the vertical plane is controlled by a mechanism of 14 s. by an eccentric, the upper disc 3 is prevented from turning by means of a key, the material is loaded through the feed funnel 15, and the finished product is removed from the device through and 16.

A device for grinding bulk materials works as follows.

The lower disk 2 and vertical shaft b get a puppy f from the drives. Through the feed funnel 15 and the loading opening 5 of the upper disc 3, material is fed into the working area. Hitting the rotating lower disk 2, the material moves to the periphery of the disks in the area between the upper 3 and lower 2 disks, the material changes with self-cutting, crushing with balls 0 and abrading the surface of the disks. The rod-axis 7 during the rotation intensively mix the material, thereby increasing the self-grinding of the material. Balls 8 cat ts in the grooves 10, grinding at

this stuff. Since the radii of the grooves 10 are larger than the radii of the balls 8 corresponding to them, the balls 8 have the possibility of self-alignment to improve the grinding process. Grooves 10 on top 3 and

The lower 2 DISKRHs are shifted in the radial direction, thereby improving the conditions for grinding the material due to more rational use of the entire volume of the working chamber. The springs 9 improve the distribution of the balls 8 along the length of the rods of the axes 7, and when the balls hit 8, pieces of material absorb shock. Balls placed on the rod x-axes of the xxxx russia run around the grooves 10 of the upper

disca 3, and the balls, placed on the rod x-axis x of the lower rus, along the grooves 10 of the lower disk 2 This increases the efficiency of grinding the material. Since smaller particles of material are necessary for

If it is more effective to grind balls of larger diameter, the balls 8 in the direction to the periphery of the discs increase in diameter. By changing the position of the lugs 11 relative to the housing 1 by the mechanism 14, the size of the discharge ring slit 4 is adjusted, which allows the desired grinding fineness to be set. In this case, the upper disk 3 is held on bolts 12. In the case of an inadmissible body entering the working chamber with

By moving under the action of centrifugal forces to the discharge ring slit 4, the indescribable body acts on the upper disk 3, which is displaced upward, having overcome the force of the springs 13 and passes the inelasticated body out of the device. The finished product enters the discharge annular gap 4 and is removed from the device sepea taps 16.
